Is this a known problem?
The manufacturer has sent NHTSA 4 service bulletins or notices for the 2020 Subaru Legacy that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
This bulletin announces availability of new door window regulator assemblies and door glass run channel seals in response to limited concerns of erratic operation of the anti-entrapment feature and / or the door glass either not closing or closing very slowly.
This announcement is in regard to settlement in a class action lawsuit for vehicles that will receive a limited warranty extension for original equipment Subaru windshields experiencing a qualifying crack.
This bulletin announces availability of new front door window regulator assemblies in response to limited concerns of erratic operation of the anti-entrapment feature and / or the door glass either not closing or closing very slowly.
If you encounter a customer complaint of a white residue build up on the rear door partition glass or interior molding, it may be crystallized salt.
What owners wrote
“The windshield developed a crack that started at the right A Pillar center of glass and is about 18" long. There are no visible "impact" points from anything hitting the glass. There is no "star" either. I did not hear anything hit the glass. The fissure just appeared one day.”

“Front windshield cracked and there was no apparent ding from rock. Crack came from side and spread quickly. I had it replaced by Subaru and 4 months later it happened again. The crack again came from the side with no reason. Two replacements out of my own pocket. My 2020 Legacy windshield must be defective”
Filed Mar 19, 2022
“A very small chip in the windshield has now turned into a large crack. The chip is 1-2mm in depth. I have never seen such a small chip turn into a crack like this.”

Should you keep driving it?
This page can't tell you that. 0 of 63 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
